My invention relates to building construcg t1on and more partlcularly to corner connectlons for intersectlng metal frame members,

similar in some respects to that shown inmy prior Patents No. 1,723,991 of August 13 1929, and Nof1,747,4=15 of February 18, 1930. In building construction, the use of metal frames for door and window openings has become a very common expedient and possesses a number of distinct advantages over the wood, and wood and metal constructions heretofore utilized.

However, considerable difficulty has. been experienced in suitably joining the separate members constituting the opening frames at their intersections. A number of devices have been presented to the trade which are intended to obviate the objections heretofore experienced but the proposition of insuring against separation of rigid intersecting elements in a simple and economical manner has been heretofore unsolved.

One of the objects of my invention is to provide a corner connection for intersecting metal frame members which consists substantially of a bendable length of wire, which does not interfere with the interfitting features of the frame members, and yet will insure a positive securing means to prevent i separation of the frame members.

Another object of my invention is to pro vide a construction which will permit the use and reception of a short length of wood block for nailing purposes when the frames i are originally set. Obviously the setting of metal frame members presents similar difficulties to the workmen and the incorporation of a wood block near the upper extremity of the vertical members provides a necessary and useful nailing means.

My invention will be more fully understood by reference to the accompanying drawings, in which 7 Fig. 1 is an end elevation of a device such as contemplated herein;

Fig. 2 is a side elevation showing the various parts of my invention in dotted lines;

' Fig. 3 is a plan view partly in section showing my device and the use of a block therer in; and

of the members.

i Fig. 4 is a sectional elevation showing a modifiedform of my invention' Obviously the two sides of the opening frame are reversed duplicates and therefore' only one sideis herein illustrated v As seen in the drawings, myinvention comprises substantially the :channel shaped header 10 and the vertical' chann'elshaped members 11' constituting the opening frames The members 1011 are of channlshape and 60:

have rebent plaster terminals 1213 formed thereon. The vertical and headrmembers are also bent to form the door stops'lt, 15;: As best seen inFig. 3 a portion at the upper extremity of the flanges 16, 17.01:" the vertical: member is struck outto form the tongues 1'8 -19 which are'bent inward and: lie in a plane substantially parallel .to the web, 20 of the vertical member 11. The header mem ber 10is provided with a pair of downwardly extending an le plates 21, 22 which provide a sliding interfitting" connection with the 'vertical member 11.; There is'alsoprovided a channel shaped connecting strip .23Ywhich joiristhe,'angleplates 21, 22 of 'the header 10. Themember 23. is-adapted to be so placed so, that the upper margin thereof will reg: isterwith the uppermargin of the tongues- 18, 19.wl1en the twoqmembers are slid into position. 1 .1 As best seen in Fig.- 3 I have fprovided: short lengths of bend-able wire which are suitably; connected to the frontv face of; the tongues 18,19. These wires are welded to the tongues at the plant and stand in avertical position such as shown in Fig.1 when, thevimembers are joined. Thereafter, thef wire is bent over the upper margin of the] member 23 .thus preventing the separation As seen," the connecting wires are ofa very' simpleform and require merely a few blowsfof a, hammer the, workman to 'firmly join the intersecting" membersa 3 My invention also contemplatesi'the insertion ofthe block245 in the spaoe betweenthe tongues 18, 19 andthe'w'eb 2 1 of the vertical member. The block is suitably h'eld in place by nails; 25 passing through registering aper-z V tures in the tongues 18, 19. and member'23. x

I have shown a modified form of my invention in Fig. 4 which contemplates the use of the nail26 driven into the block 24* and bent over the registering margins of the members 18, 19 and 23.

It is thus seen that I have provided a simpleexpedient for joining two rigid intersecting metal frame members in avery simple and time-saving manner. The wires as stated are secured at the factory when the members are fabricated and the membersneed only be slid into position and the wires bent over to insure against separation either laterally or vertically.

I claim:

' 1.- In frame construction, the combination of vertical and horizontal intersectin'gchan nel-shaped frame members, one of said members having'tongues cut out of: its flanges andbent inwardly into the plane of the web of said member, a pair of angle plates securedto the other frame member, a member joining the free portions of said plates, said" member, positioned to lie alongside of said tongues, and a length of bendable metalcarried by i the first mentioned frame member and adapted to be bent over the plate-j oining member when the partsare in final position.

2. A corner connection for intersecting metal frame members comprising a vertically disposed, channel-shaped member, tongues formed out of the flanges thereof, said tongues being bent inwardly to lie parallel with the web of said member, a second channel-shaped member adapted to slidably interfit with said first member, and a strip of wire on said tongues. adapted to be bent overv tosecurely hold said frame members against separation.

3. A corner connection for intersecting metal frame members comprisingra vertically disposed-,channel shaped member, tongues formed out' of the flanges thereof, said tongues being bent inwardly to lie parallel w v. metalframemembers comprising a vert1cal-' with the web of said member, a second channelshapedmember adapted to slidably interfit with said first member, a metal strip joining" the flanges of said-secondmember, the-- top margin thereof being adapted to registerwith said tongues, and a strip of wire on said tongues adapted'to be bent over to securely hold said frame members against separationl V e 1 4.
